An appeals court in Arizona has ordered a reassessment of the original sentence of 10.5 years in prison for Gabriel Horcasitas. According to the court, the AI video of the victim unduly influenced the judge and made the sentencing proceedings fundamentally unfair. The conviction remains in place.

An appeals court in Arizona has ordered a reassessment of the length of the prison sentence for Gabriel Horcasitas, who was convicted of killing Christopher Pelkey. He originally received the maximum sentence of 10.5 years in prison. According to the appeals court, the AI video of the victim influenced the judge so strongly that the sentencing proceedings were fundamentally unfair. The conviction remains in place.

The victim’s sister, Stacey Wales, presented the video during sentencing. She wrote the words herself and had an AI likeness of her brother deliver them, expressing forgiveness for the man who killed him. It was therefore not an actual statement by the victim. The judge explicitly praised the video and its supposed authenticity. The appeals court stressed that the situation depicted did not reflect actual events.

Wales argues that the video was only part of her statement and that the jury did not see it: it was created only after the verdict. If the appeals court’s ruling stands, she is prepared to read the same text in person. The same judge is to decide the sentence again; no firm date has yet been set.

What changed

Why it matters

The case illustrates the procedural risk of a convincing AI likeness of someone who has died: it can make words written by a bereaved family member appear to be a personal statement by the victim. The appeals court found that this format unduly influenced the judge in this case; the ruling concerns the fairness of sentencing, not the determination of guilt.

What this means

For individuals

For bereaved family members preparing victim impact statements, the case is a reminder that an AI portrayal of the victim can lead to a challenge to the sentencing proceedings, even if they wrote the script themselves.
